To all whom it may concern: I burnishing composition of commerce; Said Beit known that I, WILLIAM W. CnooKnR, l composition contains a vegetable or other of Lynn, in the county of Essex and State of Massachusetts, have invented certain new? emulsified in an alkaline substance, such as I a supcralkaline soap in solution. The composition also contains coloring-matter, such as a soluble anilin color, and a gum-like subl stance, such as shellac or gum-arabic, dissolved, preferably, by an alkaline substance, such as a solution of borax. The wholeis rc- "stains used in the operation of brushing, ducedtoasuitableliquid consistency bywater burnishing, and olishing heels and edges l or other liquid. I then evaporate the liquid and bottoms of soles of boots and'shocs, such Q from the composition byexposing the same compositions including an alkaline emulsion to the action of the air, either at its natural of wax, which is usually wax emulsified by temperature or by the aid of heat, until noththe use of a suitable substance having alkaing remains but the solid matter. line reaction, a suitable gum-like substance, I, sidumn is then pulverized, ground, or othersuch as gum-arabic or shellac, in an alkaline wise reduced to a powder, which is referor other. solution, and coloring-matter, also inl ably so fine as to be im :11 able. This dessolution, the composition having a suitable f iccated emulsii'iable b ac proportion of water to give the requisite llumaterial constitutes my improved composiidity. 'hen this composition is applied to l tion of matter and ma Y be put upon the a leather surface to be finished and a bu'rnishmarket in suitable packages. When rcing friction is appliedto such surface, a brilquired for use, it is mixed with a suitable liant gloss is raised upon the surface. Herequantity of water heated to such temperatofore finishing compositions of this kind ture as will readily take up the powder.

As a specific example of one way ofprachave been put upon the market in liquid form ready for use. The liquid composition tic-ing my invention, although I desire it understood that I do not limit myself to the has to be stored in barrels or other liquidtight packages and involves considerable ex-. substances and proportions below specified, I may take of vegetable wax one pound;

pense and loss to the manufacturer and user soap, two and one-half ounces; water, one

y reason of waste, leakage, freezing, and

gallon. The wax is emulsified by the action cost of transportation.

My invention has for its object to obviate of the-soap, and the whole is mixed, forming tlus'expenseand loss and to enable the user a liquid emulsion. To the above-described of the composition to prepare the same for use in limited quantities, such as may be required for consumption in a day or other limited period.

The invention consists in the new compo-- sit-ion of matter and in the method of 'prol ducing the same, hereinafter described and claimed, the said composition being a desiccated burnishing-powder having all the essential ingredients of the composition above described, with the water removed by evaporation and the residual material reduced to a line powder, which readily forms an emulsion in water and is adapted to be converted into mg Composition and Processes of Making the Same, of which the following is a specificatron.

This invention relates to compositions solution, consisting of one and one half pounds of anilin color and one gallon of water. I next prepare a gum-solution composed of one pound of. gum shellac, four ounces of borax, and one gallon of water. The said gum solution is then added to the above-described mixture, which is now ready for the evaporating process, which removes the liquid.-

It will be seen that this powdered composition is greatly reduced in weight compared with the liquid composition, so that the expense of transportation is correspondingly reduced. Moreover, it cannot be injuriously affected by cold and may be kept in packages which are not necessarily liquid-tight without liability of waste. The user is enabled suitable percentage of water.

In carrying out my invention I prepare in the usual or any suitable waythe ordinary A CORPORATION OF 'ng or. coloring wax emulsion is added a coloring-matter in to make up the blacking or coloring composition for use in relatively small quantities, so that freshly-prepared material can always be kept on hand. Y 5 It 1s obvious that the several ingredients of the composition may be treated separately instead of being first mixed and reduced to l the operative consistency of the completed blacking and then treated as a whole to convert it mto a powder. In other words, the wax, the gum-like substance, and the coloring-matter may be separately dissolved, evaporated, and powdered. 4. I claimr5, 1-. As a composition of matter, a powdered, emulsii'iable, desiccated blacking or coloring composition containing an intimate mixture of wax, and an emulsifying ingredient. 2o 2. As a composition of matter, a powdered, emulsifiable, desiccated blaeking or coloring composition containing an intimate mixture of wax, a suitable gum-like substance, an emulsifying ingredient, and color- 2 5 ing-matter.

3. The process hereinbefore described of making an emulsifiable, desiccated blacking or coloring composition, the same consisting in emulsifying a vegetable wax by the use of alkaline matter to form a liquid emulsion, mixing therewith a liquid solution of a suitable gumlike substance and coloring-inatter, evaporating the liquid constituents of the composition to produce a dry residuum, and powdering the said residuum.

4. In the process of making an emulsifiable desiccated blacking or coloring composition, the improved step which consists in emulsifying wax by the use of a suitable alkaline matter in water, drying the same by evaporation, and powderin the residuum.

5. 1n the process of ma ing an emulsifiable desiccated blacking or coloring composition, the improved step which consist-s in making an alkaline solution of shellac by the use of a suitable alkali, drying the same by evaporation, and powdering the residuunr- In testimony whereof l have allixed my signature in presence of two witnesses.
